Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a downlink communication including a priority indicator indicating that a first priority for a received transmission is to trigger hybrid automatic repeat request (HARQ) feedback of a first type of HARQ feedback or indicating that a second priority for the received transmission is to trigger HARQ feedback of a second type of HARQ feedback, the first type of HARQ feedback including information associated with link adaptation, the information not included in the second type of HARQ feedback. The UE may transmit the HARQ feedback, as a response to the received transmission, based at least in part on receiving the downlink communication and in accordance with whether the first type of HARQ feedback or the second type of HARQ feedback is triggered. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. For example, a method for wireless communications at a user equipment (UE), may include receiving a configuration indicating a feedback transmission scheme for reporting feedback associated with an error type. The UE may also detect an error in receiving a downlink transmission from a base station, where the detected error is of the error type. Then, the UE may select the feedback transmission scheme for transmitting a negative acknowledgement message for the downlink transmission based at least in part on the detected error being of the error type and the configuration. The UE may also transmit, to the base station, the negative acknowledgement message for the downlink transmission using the selected feedback transmission scheme.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain one or more of a number of actual bits or a number of dummy bits associated with a hybrid automatic repeat request acknowledgement (HARQ-ACK) transmission that includes one or more of a deferred semi-persistent scheduling (SPS) HARQ-ACK or a retransmitted HARQ-ACK codebook. The UE may transmit the HARQ-ACK using a power for a physical uplink control channel (PUCCH) that is based at least in part on the number of actual bits, the number of dummy bits, or a total number of bits that is a sum of the number of actual bits and the number of dummy bits. Numerous other aspects are described.

Abstract: Apparatus, methods, and computer-readable media for facilitating UE indication of SPS PUCCH HARQ feedback location are disclosed herein. An example method for wireless communication at a UE includes monitoring channel variations for SPS signaling associated with multiple SPS configurations. The example method also includes indicating a feedback occasion for providing SPS PUCCH feedback to a base station for at least one SPS configuration of the multiple SPS configurations, the feedback occasion located within a subsequent cycle.

Abstract: Embodiments include systems and methods that may be performed by a processor of a wireless device for managing a communication link with a communication network. Various embodiments may include determining whether a cause of a detected physical downlink shared channel (PDSCH) error in a downlink communication from a base station is an out of coverage condition, and initiating an autonomous handover from the base station to a second base station in response to determining that the cause of the PDSCH error is an out of coverage condition.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information for a beam report, wherein the configuration information indicates whether the beam report is associated with at least one of a subband granularity or a wideband granularity, wherein the beam report is for a reference signal received power (RSRP) measurement or a signal to interference plus noise ratio (SINR) measurement, and wherein the beam report is based at least in part on a channel state information reference signal (CSI-RS) or a synchronization signal block (SSB). The UE may determine the beam report based at least in part on the configuration information. The UE may transmit the beam report. Numerous other aspects are provided.

Abstract: Aspects described herein relate to receiving, from a base station, a hybrid automatic repeat request (HARQ) retransmission request including a HARQ retransmission offset value indicating a slot of an uplink transmission to be retransmitted, wherein the HARQ retransmission offset value indicates, based at least in part on whether switching component carriers (CCs) is permitted, the slot according to either a first numerology of a first CC or a second numerology of a second CC, and transmitting, to the base station based on the HARQ retransmission offset value, a retransmission of the uplink transmission in the slot.

Abstract: A method of wireless communication by a user equipment (UE) includes deferring transmission of a first hybrid automatic repeat request (HARQ) codebook until a target PUCCH, due to potential collision of a first initial semi-persistently scheduled (SPS) physical uplink control channel (PUCCH) with a first downlink symbol. The first HARQ codebook has a physical layer (L1) high priority. The method also includes scheduling transmission of a second HARQ codebook at the target PUCCH, the second HARQ codebook having a physical layer (L1) low priority. The method further includes multiplexing the first HARQ codebook and the second HARQ codebook to generate a combined HARQ codebook for transmission in the target PUCCH.

Abstract: Wireless communications systems and methods related to acknowledgement/negative-acknowledgement (ACK/NACK) transmissions with different reliability levels are provided. A user equipment (UE) receives, from a base station (BS), a negative acknowledgement (NACK) transmission configuration. The UE receives, from the BS, a data transmission. The UE transmits, to the BS, a physical uplink control channel (PUCCH) signal including a NACK for the data transmission based on the received NACK transmission configuration. Other aspects and features are also described.

Abstract: Apparatus, methods, and computer-readable media for semi-persistent scheduling (SPS) physical uplink control channel (PUCCH) hybrid automatic repeat request (HARQ) deferral for PUCCH groups are disclosed herein. A user equipment (UE) may receive, from a base station, a downlink configuration of a first physical uplink control channel (PUCCH) group that configures a first hybrid automatic repeat request (HARQ) feedback payload corresponding to a first semi-persistent scheduling (SPS) downlink packet for deferral and does not configure a second HARQ feedback payload corresponding to a second SPS downlink packet for deferral. The UE also may delay transmission of at least the first HARQ feedback payload based on different configurations for HARQ feedback deferral between the first SPS downlink packet and the second SPS downlink packet.
